Abstract
In this paper we tried to improve the adsorption amount by adding graphene/CNT hybrid in the structure of Activated Carbon (AC) for removing manganese ions from aqueous solutions. The bonding of G/CNT hybrid with activated carbon creates a structure that is an excellent absorbent for removing some heavy metal ions. So the Performance increasing of ion adsorption was compared with AC results as the blank adsorbent. The influence of time, pH solution, initial concentration of Mn2+ and temperature investigated as experimental conditions. The maximum adsorption was 89.38% and 96.18% for  AC and AC/G/CNT composite respectively at 30 min, initial concentration of 30 mg/L, pH=4.5 in 15°C for both adsorbents. The results showed that under the same conditions, the presence of G/CNT hybrid in the structure of AC increased the amount of adsorption by 7.5%
